如何将xml文件作为输入传递给android xml pullparser

Question

在我的应用程序中，用户可以下载存储在内部存储器中的XML文件。有没有办法通过这个文件给它的绝对路径XMLPullParser？

由于内部保存的文件，你并不需要绝对路径，你只需要在文件名：

final String xmlFile="fileName"; 
FileInputStream fis = null; 
      InputStreamReader isr = null; 
      char[] inputBuffer = null; 
      String data = null; 
      ArrayList<String> items = new ArrayList<String>(); 
      try { 
       fis = getApplicationContext().openFileInput(xmlFile); 
       isr = new InputStreamReader(fis); 
       inputBuffer = new char[fis.available()]; 
       isr.read(inputBuffer); 
       data = new String(inputBuffer); 
       isr.close(); 
       fis.close(); 
       } catch (FileNotFoundException e3) { 
       // TODO Auto-generated catch block 
        e3.printStackTrace(); 
       } catch (IOException e) { 
        // TODO Auto-generated catch block 
        e.printStackTrace(); 
       } 
      XmlPullParserFactory factory = null; 
      try { 
       factory = XmlPullParserFactory.newInstance(); 
       } catch (XmlPullParserException e2) { 
       // TODO Auto-generated catch block 
       e2.printStackTrace(); 
       } 
      factory.setNamespaceAware(true); 
      XmlPullParser xpp = null; 
      try { 
       xpp = factory.newPullParser(); 
       } catch (XmlPullParserException e2) { 
       // TODO Auto-generated catch block 
       e2.printStackTrace(); 
       } 
      try{ 
       xpp.setInput(new StringReader (data)); 
       } catch (XmlPullParserException e1) { 
       // TODO Auto-generated catch block 
       e1.printStackTrace(); 
       } 
      int eventType = 0; 
      try{ 
       eventType = xpp.getEventType(); 
       } catch (XmlPullParserException e1) { 
       // TODO Auto-generated catch block 
       e1.printStackTrace(); 
       } 
      while (eventType != XmlPullParser.END_DOCUMENT){ 
       if(eventType == XmlPullParser.START_DOCUMENT) { 
        System.out.println("Start document"); 
       }else if(eventType == XmlPullParser.START_TAG) { 
        System.out.println("Start tag "+xpp.getName()); 
       }else if(eventType == XmlPullParser.END_TAG) { 
        System.out.println("End tag "+xpp.getName()); 
       }else if(eventType == XmlPullParser.TEXT) { 
        items.add(xpp.getText()); 
       } 
       try{ 
        eventType = xpp.next(); 
       }catch (XmlPullParserException e) { 
        // TODO Auto-generated catch block 
        e.printStackTrace(); 
       }catch (IOException e) { 
       // TODO Auto-generated catch block 
       e.printStackTrace(); 
       } 
      } 
      String item1=contact.get(0); 
     String item2=contact.get(1); 
     String item3 = contact.get(2); 
     String item4=contact.get(3);
